Environmental pollution caused by plastic bags is still not small, and it is difficult to eliminate the deterioration of pollution. Urban and natural environments will cause serious pollution. Therefore, in the field of environmental protection, we attach great importance to this pollution around the world. With the rapid development of society, people have put forward new requirements and trends for plastic packaging. Environmentally friendly plastic bags are mainly the main trend of reducing quantification, harmlessness and composting.
Reduction: Reduce the production of plastic bags by consuming resources and production waste. Research, development and promotion of photodegradation using degradable plastic packaging and highly filled inorganic materials in plastic packaging can save the use of raw materials and petroleum. Not only is it vulnerable to environmental damage, but it also makes strategic use of resources.
Harmless: After testing, the study found that over time, the degradation of plastic bags and the chemical and mechanical properties of landfills have changed dramatically in the short term: completely harmless biodegradable waste, such as soil environmental capacity , Reduce waste, control environmental pollution, and finally return to the natural environment.
Compost: In recent years, waste incineration has gradually been restricted, and compost has begun to receive more attention. It can not only reduce harmful gas emissions, but also can be used as organic fertilizer to improve soil. Therefore, the development of degradable plastic bags towards composting to better meet the needs of the entire environmental protection field.
Environmental protection plastic bag production is a new member of plastic packaging products, which has effectively alleviated environmental pollution, but its production technology and applications need to be further developed, which is of great significance for energy utilization and environmental protection.
